“…This finding is in agreement with previous studies that reported footsteps as the most frequently heard noise source in Korean apartment buildings [44,53]. Carpets are not common in Korea and residents walk barefoot rather than wearing shoes; this leads to high maximum Fast time-weighted sound pressure levels at low-frequencies [54].…”

This study investigated people’s attitudes towards noise inside their homes. Online questionnaire surveys were conducted in Seoul, London, and São Paulo. The questionnaire was designed to assess annoyance caused by noise from neighbours and environmental noise (transportation). Information was also collected on situational, personal, and socio-demographic variables. Respondents that were more annoyed by outdoor noise inside their dwelling reported higher neighbour noise annoyance. In Seoul, neighbour noise was found to be more annoying than outdoor noise, and those with higher noise sensitivity reported higher annoyance towards neighbour noise. However, neighbour noise and outdoor noise was found to be equally annoying in London and São Paulo. For neighbour noise, the average percentage of respondents hearing structure-borne sources compared to airborne sources differed in each city. Most neighbour noise sources in São Paulo gave rise to higher annoyance ratings than Seoul and London. Education and income levels had a limited effect on annoyance and coping strategy. Annoyance with indoor noise from neighbours was found to have stronger relationships with cognitive and behavioural coping strategies than outdoor noise annoyance.

“…This is attributed to the different phase responses of the filters and may require future changes to the specifications for sound level meters. It has also been shown that prediction models based on a transient form of Statistical Energy Analysis can be used to predict maximum Fast time-weighted sound pressure levels in buildings with excitation form the rubber ball [37]. This approach has the potential to allow prediction of sound transmission due to both direct and flanking transmission, whereas impedance models previously focussed only on the prediction of direct transmission [38].…”

“…The force characteristics are modeled to predict the sound insulation performance of the structure by using the force as the input parameter of an analytical model. By employing this method, Robinson and Hopkins (Robinson and Hopkins 2015) estimated the sound pressure level when a rubber ball impacted a homogeneous structure. However, the limitation of this approach is that it cannot be used to evaluate the sound insulation performance of floating floors because they are commonly composed of heterogeneous materials.…”

“…To overcome these limitations, many studies have analyzed the deformation and impact force spectrum of the rubber ball approach (Park, Jeon, and Park 2010) and performed mathematical modeling of the rubber ball impacting a rigid surface (Schoenwald, Zeitler, and Nightingale 2011). Despite these efforts, there are still limitations to estimating the sound insulation performance of floating floors due to the unique characteristics of the rubber ball (Robinson and Hopkins 2015).…”

With an increasing demand for quieter residential environments, impact sound insulation for floating floors is gaining importance. However, existing methods for estimating the performance of heavy impact sound insulation are limited by their inability to comprehensively analyze various types of floating floors, as well as difficulties mathematically determining the input force of the reference source for heavy impacts. To overcome these limitations, this study proposes empirical models for estimating the sound insulation performance of floating floors under heavy impacts. The proposed models are then validated; the model with the highest accuracy exhibits an average estimation error of 2.73 dB at 50-630 Hz. The proposed models exhibit better accuracies than existing analytical models for frequencies below 100 Hz, where the estimation errors of the analytical models were large. Thus, the proposed models may help reduce errors in analytical estimates or when estimating a single numerical quantity for sound insulation rating during the design stage of multifamily housing.
